I have a 30gb Zune, and I love it. Loads songs fast, the user interface/software is really nice and simple. Videos are awesome on the Zune, the screen is nice a big, and when i download videos it will convert it to the correct format most of the time. The battery life is good, not great, if you turn off the wireless option you can get longer battery life and set the backlight lower too. I have a pioneer deck in my truck and an aux in and the zune sounds good with that, better that any fm transmitter that the overpriced car pack comes with. Ive used ipods but never owned one, they seem kinda flimsy and ive heard theyre not great with dropping them and stuff, but i cant really comment as i dont own one, I would recommend the Zune, ill buy the 80gb after i fill up the 30gb, the box says the 30 will hold like 110 hrs of video or 7500 songs, id go with the zune, my two cents
